Diabetic patients who are treated with an insulin pump can also have abnormal blood glucose. When the blood sugar is abnormal, how should we check what causes it? Xiaomai explain to you according to his experience: abnormal blood sugar is divided into factors not related to the pump, and factors related to the pump: 1, factors not related to the pump: (1) illness, infection, trauma, great mental stress, fever, etc. (2) intense emotional changes (3) female physiological phenomena: mid to late pregnancy, menstruation, etc. (4) forget to inject insulin meal before the large dose and eat (especially patients who just use the pump) (5) eat too much food after hypoglycemia caused by a significant prolonged rise in blood sugar (6) after taking certain drugs (such as glucocorticoids, diuretics, progesterone, antibiotics of the sarsen class) (7) glucose meter operating errors or malfunction The problem first from their own causes, if the cause is clear, high blood sugar plus insulin down is. 2, the factors related to the pump: If there is no above factors, you can consider the factors related to the pump. We look for the cause according to the characteristics of blood sugar. First of all, we divide the pattern of blood sugar changes into two cases according to the characteristics of blood sugar: 1) blood sugar is high and low, there are high blood sugar, there are also times when it is low. We divide the high and low blood glucose into two cases according to whether the blood glucose has a change pattern or not: (1) The blood glucose changes regularly. For example, if the blood sugar is high in the morning and low in the afternoon every day, this is called a regular pattern. This kind of regular blood glucose change should be related to the insulin dosage of the patient, and the insulin dosage should be readjusted. (2) There is no regular change in blood glucose. For example, it is high this morning and low tomorrow morning, and no pattern can be concluded. This kind of irregular blood glucose change should be related to the patient’s diet and exercise, and the diet should be adjusted. (2) Blood glucose remains high and does not drop when insulin is added. According to the relationship between blood glucose and the time of medication change, there are two types of cases: (1) Blood glucose rises immediately after changing the infusion catheter and insulin, and does not come down even after adding insulin. There may be several reasons for such cases: A. Needle not fully implanted under the skin; B. Leakage at the back end of the reservoir, the connection between the reservoir and the catheter or the catheter partition; C. Implantation on the subcutaneous nodes; D. Insulin failure. (2) After changing the infusion catheter and insulin, the blood glucose is relatively stable at first, and after staying for a few days, the blood glucose rises. Possible reasons for this type of situation are: hard nodes at the needle implantation site, etc. affecting insulin absorption. When there is an abnormal blood glucose situation, do not be anxious, analyze the possible factors provided by Xiaomai little by little, and you will surely find the cause and then solve the problem.
